人类为满足无极限的物质利益,不停顿地向自然界索取。其结果不仅使有极限的石油、煤炭、森林等资源日趋减少,而且带来能源缺乏和全球性的温室效应和环境污染等严重问题。这一点早就引起有良知的科学家们的警觉,有的已着手研究既能替代现有能源,又能减轻污染的新能源。物理学家们就是通过核裂变反应利用核裂能的,并建立了核电站。人们称此为重核裂变。可是,能产生重核裂变的资源也是有限的,不可能满足人类日益增长的能源需求,而且还有核辐射的威胁。于是,为充分利用地球上极为丰富的资源——氘,物理学家们又进行了受控核聚变的研究和试验。但是,核聚变必须在高温下才能发生反应,要求投入大量的人力、物力,耗资巨大,没有相当的经济实力是无法进行的。那么,在常温下能不能发生核聚变,做到投资小,成本低,无污染呢? 1989年3月23日,两位美国化学家——弗里斯曼和庞斯在美国犹他大学的新闻发布会上宣称,他们在装有重水的“试管”(一种简单的装置)里,通过电解,发现了核聚变现象。这一宣告,如同一场风暴,震惊了全世界的物理学界,乃至相关的科学界。至今,这场风暴尚未停息,争议仍在继续。尽管物理学家不愿承认化学家的这一发现,但是,架不住人们对于干净的新能源的渴求,许多国家都悄悄地投入人力、财力,加紧从事这?
Mankind does not stop to seek from nature in order to satisfy the limitless material interests. As a result, not only are there limited resources such as oil, coal and forests declining, but also serious problems such as lack of energy and global warming and environmental pollution. This has long aroused the vigilance of scientists with conscience, and some have started to study new energy sources that can replace existing energy sources as well as reduce pollution. Physicists use nuclear fission energy through nuclear fission reactions and have established nuclear power plants. People call this a heavy fission. However, resources that generate fissile nuclear fission are also limited, unlikely to meet the growing energy needs of humankind, and are at risk of nuclear radiation. So, in order to make full use of deuterium, an extremely rich resource on the earth, physicists conducted researches and experiments on controlled fusion. However, nuclear fusion must react at high temperatures, requiring huge investment of manpower and material resources, which is costly and can not be carried out without considerable economic strength. Then, at room temperature can nuclear fusion occur, so that small investment, low cost, pollution-free? March 23, 1989, two American chemists - Frisman and Ponce in the Utah University press release It was declared at the meeting that they found nuclear fusion by electrolysis in a “test tube” (a simple device) containing heavy water. This announcement, like a storm, has shocked the world's physics community and even the related scientific community. So far, the storm has not stopped, the controversy continues. Although physicists are reluctant to admit this discovery by chemists, they can not afford the thirst for clean new energy sources. Many countries are quietly investing human and financial resources to step up their efforts.
